Title: Improvements in or relating to pneumatic thread extractors for looms with automatic weft replenishment
IPC: D03D45/20
Filed: 1938-08-03
Abstract: 516,950. Looms with automatic weft replenishment. CROMPTON & KNOWLES LOOM WORKS. Aug. 3, 1938, No. 22919. Convention date, Feb. 10. [Class 142 (iii)] Pneumatically controlling the weft ends from ejected bobbins ; weft, cutting. When the transferer descends to insert a reserve bobbin into the shuttle, a projecting arm 49 frees the arm 46 of a lever 40, which is thereupon rocked by a spring 42 and a cutter 44 is carried into position to co-operate, when the lay is forward, with a plate 45 on the shuttle. The thread or weft end W of the ejected bobbin, which extends from the shuttle eye E over the plate 45 to the selvedge, is thus cut near the shuttle eye. Also a cam plate 84 on the transferrer acts on a roller 83 on an arm 70 on a holder 71, rocks this against the action of a friction washer and disc spring on to its pivot, and a tube 90 of a thread extractor is lowered so that a lip 94 at its flattened mouth end is caused to dip into friction material such as pile fabric 61 inserted in a well in the lay. The tube 90 is connected by a flexible hose 91 to a weft end accummulator which communicates with a pump. As'the lay recedes, the thread W, which is temporarily clamped between the shuttle and friction material such as fur 112 on the shuttle binder and is held frictionally on the top of the fabric 61, enters notches 98 in the side walls of the tube at its mouth 99, and when the shuttle is picked and the right hand part of the weft end is released, this is sucked into the tube and drawn towards the accumulator, the piston pump being reciprocated by connection with the lay so that there is a maximum suctior at this period. During the backward movement of the lay, the angular position of the weft end changes and it enters an undercut slot 64 under the box mouth 65 of the shuttle box prior to being picked up by the extractor. As the lay recedes further, a resetting screw 80 engages and rocks the holder 71 and the extractor 90 is raised to its normal position clear of the shuttle path, the thread W extending from the selvedge into the extractor being above and free from the second thread W' extending from the fresh bobbin inserted into the shuttle. Some picks later, the thread W is cut by the temple cutter and is drawn completely into the tube 90. The raising of the extractor causes the thread W to be held in a favourable position for being cut by the temple cutter 51, which also cuts the second thread W. This is drawn along a path below the thread W by mechanism such as the pneumatic thread holder described in Specification 503,063. The pump has a spring controlled valve, which opens when a vacuum is created but closes on the return stroke to prevent the pump blowing air out of the tube 90. The piston also has a valve. Specification 517,757 also is referred to.

[Also in Division E1] A shelf or rack structure includes carriers for stored articles, e.g. pallets, carried by concrete pillars disposed side by side in a row so that together they define a wall in which vertical webs of the pillars are aligned in the plane of the wall. In one arrangement the pillars may be of X, T, L, H or U-shaped cross-section with aligned webs 1, 1<SP>1</SP> or 3, 3<SP>1</SP>, Fig. 3, and transverse webs 2 or 4, and have integral formations or attachments along their length to support shelves or bearer beams 5 at adjustable height. Two pillar sections may be superposed. Another form of pillar 11-15, Fig. 6, has a rectangular box section. Cantilevered arms 16 interconnected by cross-beams 17 are secured on one or both sides of the wall by bolts (20, Figs. 10-12) passed through the wall between adjacent pillars. In another form, Fig. 13, the pillars 31, 32 comprise a web 321 provided with channelled longitudinal edges 322, 322<SP>1</SP> defining grooves filled with concrete 340 when the wall is assembled.

Abstract: 934,422. Railway vehicle draw gear: shock absorbers. DOWTY HYDRAULIC UNITS Ltd. Oct. 3, 1960 [July 3, 1959], No. 23002/59. Classes 103(5) and 108(3). A railway vehicle having a headstock 3 mounting side buffers is provided with an automatic inclined swing coupler 1 which may pivot about vertical and horizontal axes intersecting at the point 4, the coupler being carried by a drawbar 2 which may move inwardly from the normal position shown, where the buffers are in contact, and also outwardly from the normal position against a snatch spring 12 and the action of a hydraulic damper 18, 23. The coupler is supported in the horizontal position by a caged spring device 6 pivotally mounted on trunnions 8 supported in brackets 9 as described and shown in Specification 876,173. The drawbar 2 has a pressure plate 13 which bears against a shoulder on a piston rod 14 fixed on the bar 2, and a bearer plate 16 is also provided. The hydraulic damper comprises a cylinder 18, filled with liquid to the level 26 shown and provided with a tapering groove 27, and a piston 23 provided with a spring pressed valve plate 25 controlling fluid flow through holes 24. If the vehicle is buffed the energy is absorbed by the side buffers, and the drawbar 2 moves inwardly so that a slight pre-compression of the spring 12 is relieved and the piston 23 moves towards the base of the cylinder 18 without appreciable resistance. On recoil of the buffers, the drawbar 2 will travel outwardly under the tension load in the drawbar at a rate which is limited by the hydraulic damper.

Abstract: 1,048,083. Work benches. AMP Inc. Sept. 10, 1964 [June 12, 1963], No. 23327/63. Heading B4X. In a method of effecting electrical wiring of terminals or posts closely spaced in groups on a panel, the panel is supported on the platform of a co-ordinate plotting device, the selected terminals being identified by a pair of frame members XA, YA arranged orthogonally in a plane parallel to the panel, the frame members being adapted to move mutually transversely to a position at which they cross at or adjacent to a terminal to be connected, by driving means operable to a predetermined programme. A second set of frame members XB, YB driven in response to the programme is provided to enable a pair of co-ordinate points between which a lead is to be connected, to be indicated simultaneously. The frame members comprise tensioned wires stretched between supports which may include trolleys running on rails or lead screw mechanisms for traversing the wires in relation to the panel. One frame wire of each pair is spaced further from the panel than the other. In the case of a set of two pairs of frame wires one pair is spaced further from the panel than the other. The pairs of wires may frame a rectangle in order to allow access to a terminal. Means for testing the connection to each pair of terminals comprises rigid frame members below the panel and corresponding to the frame wires above the panel. The system below the panel is arranged to move solenoidactuated plungers to points corresponding to the terminal or post positions. In a modification, the co-ordinate locating machine may comprise a row of push-button switches arranged along X and Y co-ordinate axes at the sides of a plotting board and arranged to control the operation of the drive for moving the frame wires across the board. The operator may read off the co-ordinate of the post to be connected from a suitable chart by pressing electric push-buttons corresponding to the co-ordinates.

Convention date, Aug. 10, 1929. [Class 8 (ii).] A cutter b for the sealing disc a<3> of a fluid container a, such as a fire-extinguisher, is normally urged towards the disc by a spring d, but is restrained by the engagement of a shoulder b<4> on the cutter stem with a flat e<1> on a spindle e journalled in the cap member c. The engagement of the shoulder with the flat is such that the spindle tends to rotate under action of the spring d. To prevent such rotation, an arm e<3> fixed on the spindle engages an arm f<2> on a pivoted lever f that is held against counterclockwise movement by a tensioned cable f <3>. When the cable is released, the lever f is free to move, releasing the spindle e and cutter h. When the apparatus is out of use, a locking bar f<5> prevents release of the spindle. The cutter stem is guided by a pin b<6>, Fig. 1, or by a restriction b<8> in the cap c, Fig. 3. The fluid is discharged through the hollow perforated cutter to an outlet port c<3> or c<4>.
